In June 2012 had a crown put on dentist drilled filling out no root canal. First crown defective hole in it, so put a temp on until new one made. Now I have pain and he is saying sorry you need a root canal your tooth is dying, but he couldn't tell by looking at xrays he tapped it, he is going to charge me the same as the first procedure on the same tooth. I feel this was his error and he should have done root canal to begin with. I do not feel I should spend double on one tooth.
